Abstract

This invention provides a method and apparatus to eliminate the theft of various types of electronic equipment through the use of an existing telephonic connection. The method includes steps of determining an apparent theft, contacting a local police or security authority and providing a means of discovering the location of the stolen equipment. The method further allows the apparatus to eliminate the need for excessive hardware components by utilizing pre-existing infrastructure. In utilizing preexisting infrastructure, the invention allows operation in a plurality of locations through its stand-alone capabilities and location identification capabilities.

Claims

1. An antitheft device for use in portable electronic equipment comprising a microprocessor and a communication module for connection to an external communication network, said microprocessor including a telephone number indicative of the location of said electronic equipment, an output to provide said telephone number to said communication module and a comparator to compare a response from said communication module to a predetermined response and thereby determine whether said equipment is in a desired location;

wherein said predetermined response is a busy signal from the external communication network.

2. An antitheft device according to claim 1 wherein upon receipt of a response other than said predetermined response said microprocessor utilizes additional data with said external communication network to indicate a theft of said equipment.

3. An antitheft device according to claim 2 wherein said additional data is a telephone number of a security authority.

4. An antitheft device for use in portable electronic equipment comprising a microprocessor and a communication module for connection to an external communication network, said microprocessor including data indicative of the location of said electronic equipment, an output to provide said data to said communication module and a comparator to compare a response from said communication module to a predetermined response and thereby determine whether said equipment is in a desired location;

said antitheft device further comprising user-accessible software allowing said data indicative of the location of said electronic equipment to be modified by a privileged user.

5. A method of detecting the theft of portable electronic equipment using an antitheft device associated with the portable electronic equipment, the method comprising the steps of:

(a) providing data indicative of a desired location of said electronic equipment to an external communication network, from said antitheft device;

(b) comparing a response from said external communication network to a predetermined response;

(c) acknowledging the removal of said electronic equipment from said desired location if said response from the external communication network differs from said predetermined response; and

(d) sending additional data to said external communication network indicating the theft of said electronic equipment if said response from said external communication network differs from said predetermined response;

wherein said additional data also includes data for determining the present location of said electronic equipment.

7. The method of claim 5 wherein steps (a) to (d) are repeated on a periodic basis.

6. A method of detecting the theft of portable electronic equipment using an antitheft device associated with the portable electronic equipment, the method comprising the steps of:

a providing data indicative of a desired location of said electronic equipment to an external communication network, from said antitheft device;

(b) comparing a response from said external communication network to a predetermined response;

(c) acknowledging the removal of said electronic equipment from said desired location if said response from the external communication network differs from said predetermined response; and

(d) modifying the desired location of said electronic equipment whenever prompted by a privileged user.
